Microbial Fuel Cell

About Microbial Fuel Cell

Introduction:

The concern of depletion of fossil fuel supplies and fossil fuels effect on climate change made the scientist to search for alternative source of energy. Nowadays, energy production and wastewater treatment have become critical issues for environmental and energy sustainabilities and because of this microbial fuel cells (MFCs) have gained much attention as a new method for simultaneous electricity generation and wastewater treatment.

The MFC operates the same as a chemical fuel cell except for the anode part, microbes perform the role of anodic catalyst but still MFC is not considered as a commercial operation The most important parts of an MFC are cathode catalyst, proton exchange membrane (PEM) and the anodic biocatalyst and about 90% of the capital cost of MFC is due to high price of cathode catalyst and PEM which has led to more research on developing new types of economically viable membranes and inorganic cathode catalyst which is the long-term goals of MFC operation.
